Abstract

Dans un procédé de séparation d'air par distillation cryogénique, de l'air (7) comprimé, épuré et refroidi est envoyé à une première colonne (1) d'une double colonne, la première colonne opérant à une première pression et étant reliée thermiquement à une deuxième colonne (3) de la double colonne opérant à une deuxième pression, inférieure à la première pression, un liquide riche en oxygène et contenant du krypton et du xénon (13) est soutiré de la cuve de la deuxième colonne et envoyé à une unité de traitement (21), un liquide riche en oxygène (19) est soutiré de la deuxième colonne caractérisé en ce que le liquide riche en oxygène est soutiré de la deuxième colonne à un niveau juste en dessous du tronçon d'éléments d'échange de masse le plus bas (25) de la deuxième colonne.
